From late 40 with better electronic and better skilled crew they get smart, zigzagging towards u until they are below the minimum range for arming the eals. Then they go straight for u with flank and try to overun and wabo ure sorry bud. No frigging way to to hit them unless u throw a full spread of eals at them before they are too close.
I consider only an attack as long as im not spotted yet. One exception is attacking a flowerpot with the deckgun. With a superb trained crew in ure boat it has no chance but to run away to survive
another one is after they ran outta wabos. With some patience at night sitting at 18m u can kick their bud without using the scopes.
